Abstract
The life-history of Haplorchoides mehrai Pande & Shukla, 1976 is elucidated. The cercariae occurred in the thiarid snail Melanoides tuberculatus (Muller) collected from Chilka Lake, Orissa State. Metacercariae were found beneath the scales of Puntius sophore (Hamilton). Several species of catfishes in the lake served as definitive hosts. All stages in the life-cycle were successfully established under experimental conditions in the laboratory. The cercariae are of opisthorchioid type with a large globular and highly granular excretory bladder and seven pairs of pre-vesicular penetration glands. The adult flukes are redescribed to include details of the ventro-genital complex. Only three Indian species of the genus, i.e. H. attenuatus (Srivastava, 1935), H. pearsoni Pande & Shukla, 1976 and H. mehrai Pande & Shukla, 1976, are considered valid, and the remaining Indian species of the genus are considered as species inquirendae. The generic diagnosis of Haplorchoides is amended and the genus is included in the subfamily Haplorchiinae and the family Heterophyidae.
